net.wars: Scanning the TSA

There are, Bruce Schneier said yesterday at the Electronic Privacy Information Center mini-conference on the TSA (video should be up soon), four reasons why airport security deserves special attention, even though it directly affects a minority of the population. First: planes are a favorite terrorist target. Second: they have unique failure characteristics – that is, the plane crashes and everybody dies. Third: airlines are national symbols. Fourth: planes fly to countries where terrorists are.

Without the sign, if you saw someone heaving stones at the cars you'd call the police. With it, you peer nervously at the truck in front of you. Does that driver look trustworthy? This is, Schneier said, counter-productive because what people report under that sort of instruction is "different, not suspicious".

But the bigger flaw is cover-your-ass backward thinking. If someone tries to bomb a plane with explosives in a printer cartridge, missing a later attempt using the exact same method will get you roasted for your stupidity. And so we have a ban on flying with printer cartridges over 500g and, during December, restrictions on postal mail, something probably few people in the US even knew about.

Technology, Lillie Coney observed, has become "like butter – few things are not improved if you add it."

If you're someone charged with blocking terrorist attacks you can see the appeal: no one wants to be the failure who lets a bomb onto a plane. Far, far better if it's the technology that fails. And so expensive scanners roll through the nation's airports despite the expert assessment – on this occasion, from Schneier and Ed Luttwak, a senior associate with the Center for Strategic and International Studies – that the scanners are ineffective, invasive, and dangerous. As Luttwak said, the machines pull people's attention, eyes, and brains away from the most essential part of security: watching and understanding the passengers' behavior.

"[The machine] occupies center stage, inevitably," he said, "and becomes the focus of an activity – not aviation security, but the operation of a scanner."

Equally offensive in a democracy, many speakers argued, is the TSA's secrecy and lack of accountability. Even Meera Shankar, the Indian ambassador, could not get much of a response to her complaint from the TSA, Luttwak said. "God even answered Job." The agency sent no representative to this meeting, which included Congressmen, security experts, policy scholars, lawyers, and activists.

So then, what are the alternatives to spending – so far, in the history of the Department of Homeland Security, since 2001 - $360 billion, not including the lost productivity and opportunity costs to the US's 100 million flyers?

Well, first of all, stop being weenies. The number of speakers who reminded us that the US was founded by risk-takers was remarkable. More people, Schneier noted, are killed in cars every month than died on 9/11. Nothing, Ralph Nader said, is spent on the 58,000 Americans who die in workplace accidents every year or the many thousands more who are killed by pollution or medical malpractice.

"We need a comprehensive valuation of how to deploy resources in a rational manner that will be effective, minimally invasive, efficient, and obey the Constitution and federal law," Nader said.

So: dogs are better at detecting explosives than scanners. Intelligent profiling can whittle down the mass of suspects to a more manageable group than "everyone" in a giant game of airport werewolf. Instead, at the moment we have magical thinking, always protecting ourselves from the last attack.

"We're constantly preparing for the rematch," said Lillie Coney. "There is no rematch, only tomorrow and the next day." She was talking as much about Katrina and New Orleans as 9/11: there will always, she said, be some disaster, and the best help in those situations is going to come from individuals and the people around them. Be prepared: life is risky.
